u This invention relates to' spools andbobbins of the character employed in textile It aims to provide spoolsand bobbins of improved construction, rendering them sub-` stantially non-breakable yand durable under usage conditions in the various textile-mill operations or practices offeeding'yarn for.

cloth andfabric weaving. l y n The invention will be best understood by reference to the accompanying drawings illustrating embodiments thereof with certain modications. In said drawings: f Fig. l is a perspective view inl illustration of a spool with head and fastening plug at one endin applicative relation to the barrel, the parts being shown vin transverse section;

Fig. 2 is an elevation representing a finished spool, the united parts being shown in transverse section; .e

Fig. 10 represents an end view of afinished spool'xoif the modified construction Referring to the lrawings,' 11 denotes the wooden barrel or stale of a spool or bobbin. Saidy barrel is shown centrally vbored to tubular form and havinga recess or crevice 12 in its end extending substantially con# centric with but spaced-from its bore, i. e., a portion of. the tubular wallv of the barrel 'separates the recess from the bore.y

In this instance said recess is annular, but

may advantageously be made polygonal inf` v stead. In certain instances it may be desir able to provide aseries of recesses'in spaced y', relation'annularly of the barrel bore in place' of the continuous recess shown.' However, upon modifying the character of the recess in either of the ways mentioned, the form of n the fastening plug hereinafter described must be correspondingly modified as will become obvious.

Accordingly, the barrel end is bifurcated or formed with substantially double kwall portionsllaa-nd 1,11?, which in the illustra- 1 tive construction appear as concentric tubular extensions of the barreland this form isother toughand non-'brittle composition re-V sisting breakage. Such. headsarewcutf or lpunched from` slabs ofl the component mate.

From the-foregoing, it Will be understood that the ribs are of ytapering tudi-nal section. 1
